IMPROVEMENT IN HORSE HAY-RAKES.

Specification forming part of Letters Patent No. 210,093, dated November19, 1878; application filed September 28, 1878.

To all whom it may concern Be it known that 1, DICKERSON A. GAL- KINs,of Monson, in the county of Hampden and State of Massachusetts, haveinvented certain new and useful Improvements in Horse Hay-Rakes and I dohereby declare that the following is a full, clear, and exactdescription thereof.

This invention relates to certain improvements in horse hay-rakes; andthe invention consists in the construction and arrangement of parts,which will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make,

, construct, and use the same, I will now proceed to describe itsconstruction and operation, reference being had to the accompanyingdrawing, which forms a part of this specification, and in which- Figure1 is a front view with the shafts removed. Fig. 2 is a perspective viewwith the wheels and teethcarrier removed. Fig. 3 is a back view with theteeth raised. Fig. 4 is a section through one of the friction-clutches,

wheel-hubs, and teeth-carriers. Fig. 5 is a front view of one of thefriction-clutches. Fig. 6 is a section taken on line as wof Fig. 1. Fig.7 is a view showing the teeth held just above the ground by the buttonarranged under the cross-frame, and Fig. 8 is a view showing one of theclutches that connect the shafts to the rake-head.

In the drawing, A denotes the rake-head. This rake-head is formed withsolid ends B, (shown in Fig. 4 of drawing,) having-spindles 0, uponwhich the wheels D are arranged.

The hubs E are formed. with projecting boxes F, which pass into a recessformed by the spindle O and flange G of the solid end of the rake-head.

The teeth H are loosely pivoted to bolts I, (shown in Figs. 3 and 4 ofdrawing,) passing through the rake-head A and secured by nuts J. Theteeth pass through slots K (shown in Fig. 6 of drawing) in the bar L,which is held by stiff arms M, extending out from the rakehead A, asshown in Figs. 3 and 6 of drawing.

The slots K are vertically elongated in order to allow an upwardmovement of the teeth 4 of drawing.

when caught or obstructed by some impediment.

Upon each end B of the rake-head is arranged a standard, N, constructedto receive astandard, 0, (shown in Fig.4 of drawing,) the lower end, P,of said standard N being held by screws or bolts Q, as shown in Figs. 1and 3 of drawing. These standards N support a cross-frame, R, upon whichis centrally arranged a seat-box, S, having the seat T supported thereonby coil-springs a, as shown. The cross-frame is also provided with afootboard, U, extending out in front of the seatbox S, as shown in Figs.2 and 6 of drawing, the forward end of the foot-board U being supportedby standards V, extending up from the I shafts W, as shown in Fig. 6 ofdrawing.

The shafts W are secured to the rake-head A by spanning-irons X,arranged in a circumferential groove, 1). (Shown in Fig. 4 of drawing.)These spanning-irons X are secured to the ends of the shafts W by screwsor bolts, as shown in Fig. 8 of drawing.

To the cross-frame R, under the seat-box S, and near one side thereof,is fulcrumed a lever, Y, the long end of which passes through a slot, 0,in the side of the seat-box S, and a slot, d, in one of the seat-boxbraces e, as shown in Fig. 2 of drawing. The short end of the leverunder the seat-box connects with avertical arm, f, (shown in Fig. 1 ofdrawing,) extending up from a toggle-joint, 9, supported by the frame itunder the cross-frame R, as plainly shown in Fig. 1 of drawing. To thelower ends of the two arms of the toggle-joints is secured one end oftwo horizontally-arranged arms, 1', extending in opposite directions tothe friction-clutches j, arranged on the solid ends B of the rake-headA, as shown in Fig.

the friction-clutches by spanning-arms k, as shown in Figs. 1 and 3 ofdrawing. The fric tion-clutches j are held and allowed to slide, butprevented from turning on the solid end B, by a rib, l, as shown in Fig.4 of drawing. To the rake-head A is secured an arm, m, which, when theteeth are elevated, engages and is held by the projecting end a (shownin Fig. 6 of drawing) of the spring-catchb, arranged under the seat-boxS, as plainly shown The aFms t are connected with in Fig. 2 of drawing.This catch 0 may be locked down when desired, to prevent it frominterfering with the movement of the rakehead A by a spring-lock, 10,(shown in Figs. 1 and 2 of drawing,) when it is desired to elevate andlower the teeth by the lever Y. The teeth are held down in position,when it is desired to rake, by an arm, q, extending up from therake-head A, as shown in Fig. 1 of drawing, which engages with the hook'r, pivoted to the cross-frame R. The hook r is operated by a rod, 8,extending from the lever Y, as plainly shown in Fig. 2 of drawing.

In some cases it is desired to carry the teeth just free of the groundwhile raking. This may be accomplished by the buttons t, secured to theunder side of the cross'frame B. When such elevation of the teeth isrequired, the buttons t are turned out and engaged with the arms q, asshown in Fig. 7 of drawing.

The teeth are operated in the following manner: When it is desired toelevate the teeth in order to drop the accumulated hay thereon, thelever Y is pulled toward the seat. By this movement of the lever thefriction-clutches are, by means of the toggle-joint and horizontal arms,shoved out and made to engage with the hub of the wheels, which, as theyrevolve on the forward movement, turn the frictionclutches, which, inturn, revolve the rakehead until the teeth are elevated to their highestpoint.

If it is desired to carry the teeth elevated,

the catch 0 is disengaged from the lockp, and thereby allowed to springits projecting end a down on the arm m, as shown in dotted lines of Fig.6 of drawing.

When it is desired to lower the teeth for gathering the hay, thefriction-clutches are disengaged by shoving the lever from the seat.This movement allows the teeth to drop down in position, when the arm qis caught by the hook 1", which rigidly holds the teeth while gatheringthe hay.

The arms u, (shown in Fig. 6 of drawing,) extending backwardly from thecross-frame, shove the hay from or off of the teeth when they areelevated.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The combination of the lever Y, rod 8, and pivoted hook r with thearm q and rakehead A, as set forth.

2. The combination of the catch 0, lock arm m, and rake-head A, as setforth.

3. The combination of the buttons t, arms q, and rake-head A, as setforth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
